AN'JISLIPPING DEVICE.

Application filed July 25, 1923. Serial No. 653,817.

T @ZZ whom t may concern:

Be it known that I, BRANTLEY EAST, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented certain new and useful Improvements in Antislipping Devices, ofwhich the following is a specification. y

This invention has for Vits principal object to provide an attachmentwhich may be readily applied to a boot or shoe for use when walking on4ice or upon smooth, slippery places and which may be convenientlyremoved. The invention includes a toothed contact-plate of invertedU-shape and a resilient pad or block, operating as a cushion, the latterbeing disposed between the plate and the shank of the shoe, means beingprovided for maintaining these parts at the front of the heel with thecushion in engagement with the shank, the proportion of parts being suchthat the wings of the plate will normally be disposed in a plane lowerthan the bottom of the heel i`or engaging ice or the like, to preventslipping, the block or cushion operating automatically to permit theplate, together with its toothed wings, to move upwardly when the weareris walking upon a floor or other indurate surface.

The invention consists of the novel construction, combination andarrangement of parte as described herein and claimed, and as illustratedin the accompanying drawing, wherein,-

Fig. 1 is a side view of a shoe with the attachment applied thereto.Fig. 2 is a sectional view through the attachment on line 2 2 of Fig. 4.Fig. 3 is a side view of the device, disposed in its normal position atthe front of the heel, th-e shank and part of a shoe being in section.Fig. 4y is a plan view of the device, a strap being shown in transversesection. Fig. 5 is an end view of the contact-plate. Fig. 6 is asectional view on line 66 of Fig. 7. Fig. 7 is a plan View of thecontact-plate. Fig. 8 is a view of the device in transverse section, online 8-8 of Fig. 2.

Referring now to the drawing for a more particular description, numeral9 indicates a resilient block or cushion, adapted to be disposed upon aplate 10 approximately of inverted U-shape, and to be secured at thefront of the heel 11 in engagement with the shank 12 of a shoe 13,holder a strip 14 being employed for maintaining the parts in thepositions mentioned, lsaid strip preferably being providedr with a loop15 and a strap 16, both operating, when mounted on the shoe, to presstheplate upwardly against the block and to press'the block against theheel and shank of the shoe.

ln order that the parts will not become detached from the shoe whenworn, and to the end that manufacture may be economical and convenient,certain features are provided, and to be described. The cushion 9,

preferably, is provided longitudinally, in its top, with a groove orchannel 17 (Fig. 8.) for receiving a part of the strip 14, and isprovided with projections 18 which eX- tend from its bottom. Numerals 19(Fig. 7.) indicate apertures formed in the contactplate for receivingthe projections 18, said plate also having slots 20 formed transverselytherein, near its ends, for receiving part-s of said strip 14, theopposed wings of said plate, preferably, having projections or teeth 21,as best shown in Fig. 3.

The device may be readily attached to a boot or shoe. The bucklev 22being unfastened, the loop 15 may then be placed over the instep, andthe cushion may be placed below the shank of the shoe at the front ofthe heel, and by use of member 16 in a well known manner, thecontact-plate and cushion may be secured in their normal positions. j

It will be seen that the parts will not become detached during use sincethe strip 14 is disposed in the groove 17 in the top of the cushion, andengages the ends of said cushion, and also engages in the slots 20 ofthe contact-plate; and on account of the arrangement of these parts, andsince the projections 18 of the cushion engage in the apertures 19 ofthe contact-plate, any transverse movement of this plate relative to thecushion, will be prevented. It will be noted that the width of thecushion is greater than the width of the contact-plate, the result inoperation being that the wings and teeth of the contact-plate will bedisposed forwardly of the heel 1l to permit the teeth to engage ice orother slippery surfaces to advantage.

It is understood, of course, that the cushions may have any requiredthickness, depending upon the height of the heel, so that theprojections 21 will normally engage and will be pressed into the ice orother 'yielding surface by action of the resilient block, so thatslipping will be prevented.

Among some ol the advantages to be derived by use of the invention, itmay be stated that the attachment consists ot few and simple parts, andmay be manufactured economically; also it will be durable in wear andmay be conveniently attached to or removed from boots or shoes. lnmanufacturing the cushions, ample provision is made so that they willhave various degrees ot thickness corresponding` with the height ot shoeheels, it beingnecessary to operation that the teeth or wings ot thecontact-plate shall normally project downwardly in a plane somewhatbelow the bottom of the heel.

The groove 17 in the top of the resilient block, while preferred, couldbe omitted; and while it is preferred that the plate be provided withthe projections 2l, the device would be operative, inv a measure, if theprojections were omitted, and it will be understood that changes intorin, size, and

proportion of parts and minor details may be made, these changes beingdetermined by the scope of the invention as claimed.

l claim as my invention,-

ln anti-slipping device, the combination with a holder-strip for amount-ing on the shoe, of an elastic block for engaging that part of theshoe below the shank, said block having a groove opening on its topbetween it sides and havingprojections extending` from its bottom, and ametallic plate pro vided with slots and having depending projections andprovided with apertures and eceiving the projections ot' said block,said holder-strip being movably mounted in the slots ot said plate andengaging in the groove of said block.

ln testimony whereof, l have aHiXed my sigejnatnre in presence ot twowitnesses.

BRANTLEY EAST.
